Circular production chains : a micro and meso approach
No full textCircular economy (CE) aims to create a sustainable economy while keeping economic growth intact, by internalizing negative externalities, such as waste. Research on this subject has come far on the macro level (e.g., legislative recommendations) and the meso level (e.g., life cycle engineering (LCE), circular supply chain (CSC), and circular value chain (CVC)), but less so on the micro level (i.e., the level of the individual firm). The issue this creates is that the businesses (which are the very basis of the economy) do not have clear frameworks, guidelines, or tools to reshape their own business in such a way that they can participate in a circular economy, hence hampering the development of a circular economy. In this research, we have created a circular production chain (CPC) that takes into account the resources, production process, product, and waste a company produces, through three aspects: imput, design, and output, but also places the company in the bigger picture, that is, the economy, and shows how CE is achieved by multiple companies working together, highlighting the importance of tactical management. In the process we uncover three main influences that facilitate or inhibit the implementation of CE practices in a single business
Denica 2.0 and Tactical Management Information System (TMIS)
No full textMiddle managers are often operating in complex and fast-moving environments, resulting in having to deal with enormous challenges in a short span of time, maneuvering diverse and numerous “givens” and aiming to achieve specific goals. These challenges are very diverse and require support tailored to the needs and characteristics of middle management. Due to the lack of tailored tools, middle managers often use methods that were originally designed for strategic or operational management, which they then adapt as best as possible to fit their tactical management needs. We thus see middle managers as the prototype of managers that have tactical management responsibilities, even though tactical management issues are also faced by executive, operational, and project managers. In a fast-changing world, heavily impacted by globalization and digitization, adaptability is one of the most essential characteristics of a middle manager. However, because of the lack of methods and systems tailored specifically to the tactical management level, middle managers are often not sufficiently supported to be able to deal with numerous givens, unpredictability, and a dynamic, turbulent, and complex environment. Hence, they lack proper support for being adaptable
Defining sharing economy, marketplace and other service platform related concepts : a reference ontology approach
Full text linkThe value management platform and ArchiMate : towards an integration? An illustrative example for value stream mapping
Full text linkThe Value Management Platform (VMP) of VDMbee is one of few strategy and business model development tools that were inspired by the Object Management Group's VDML standard for value modeling. ArchiMate is The Open Group's specification of an enterprise architecture language that goes well together with their TOGAF framework, which is widely used by enterprise architects. Although VMP and ArchiMate were developed for different reasons, the evolution of both enterprise engineering instruments seems to converge towards a large(r) common ground. For instance, the most recent addition to ArchiMate is the Value Stream element, allowing ArchiMate to be used for value stream mapping (in line with TOGAF), for which support is also provided by the VMP. As another example, VMP now integrates the Process Designer tool which allows generation of BPMN 2.0 business process diagrams from value stream maps. Despite this observed convergence, each approach has its own purpose like providing a framework for strategy planning and execution for VMP and providing structure and context amongst the many artifacts that comprise an organization’s architecture for ArchiMate. In this paper, we question whether the integration of both instruments would be useful for practice and present a scientifically viable research topic. As a preliminary, but necessary, step for any kind of integration, we propose to investigate how VDML (and other) artifacts underlying enterprise modeling with VMP map onto ArchiMate. As an illustrative example, we demonstrate how value streams designed with VMP can be visualized with ArchiMate
Beyond Language Independent Object-Oriented Metrics: Model Independent Metrics
No full textSoftware Metrics have become essential in software engineering for several reasons, among which quality assessment and reengineering. In the context of the European Esprit Pro ject FAMOOS, whose main goal was to provide methodologies for the reengineering of large industrial software systems, we have developed the Moose Reengineering Environment, based on the language independent FAMIX metamodel. Moose includes a metrics engine which supports language independent metrics, since coping with software written in different implementation languages was one of the project's main constraints. Our current research is pushing us towards the development and implementation of a metametamodel, which would include our metamodel and allow for several extension in different research directions, among which concept analysis, knowledge management and software evolution. In this article we want to present our current and future work for the transition from language independent to domain independent metrics
Understanding business domain models: the effect of recognizing resource-event-agent conceptual modeling structures
No full textIn this paper, the author investigates the effect on understanding of using business domain models that are constructed with Resource-Event-Agent (REA) modeling patterns. First, the author analyzes REA modeling structures to identify the enabling factors and the mechanisms by means of which users recognize these structures in a conceptual model and description of an information retrieval and interpretation task. Based on this understanding, the author hypothesizes positive effects on model understanding for situations where REA patterns can be recognized in both task and model. An experiment is then conducted to demonstrate a better understanding of models with REA patterns compared to information equivalent models without REA patterns. The results of this experiment indicate that REA patterns can be recognized with minimal prior patterns training and that the use of REA patterns leads to models that are easier to understand for novice model users
